When 12x² + kx + 3 and 3x³ + (3k + 2)x² + 28x +17
Naily [24]

Answer:

\boxed{\sf \ \ \ k=5 \ \ \ }

Step-by-step explanation:

Hello,

We know that for a real, the polynomial P(x) divided by (x-a) the remainder is P(a)

and as

3x+2=03x=-2x=\dfrac{-2}{3}

so we need

12(\dfrac{-2}{3})^2+k(\dfrac{-2}{3})+3=3(\dfrac{-2}{3})^3+(3k+2)(\dfrac{-2}{3})^2+28\dfrac{-2}{3}+17\\ \ multiply \ by \ 9\\ 12*4-6k+27=-8+4(3k+2)-28*2*3+17*9\\ -6k+48+27=-8+12k+8-168+153\\ -6k+75=12k-15\\ 18k=75+15=90\\ k = \dfrac{90}{18}=\dfrac{15}{3}

hope this helps

sergejj [24]

Answer:

130 calories in the ice cream and 500 calories in the pie.

Step-by-step explanation:

Let the amount of calories in the scoop of ice cream be x. the amount of calories in the piece of pie be 3x-20. we know that x+3x-20=500.

4x-20=500

If we add twenty to both sides, we end up with:

4x=520

Divide both sides by four, and you get x=130.

there are 130 calories in the scoop of ice cream and 130*4-20=500 calories in the pie.
